Mustang-Seminole 115 kV Transmission Line Project

Xcel Energy is planning to construct a new 115 kilovolt (kV) electric transmission line in Yoakum and Gaines County, Texas.  The Mustang-Seminole 115 kV transmission line project consists of approximately 20 miles of new transmission line between the existing Mustang Substation, located just over five miles east of Denver City to the new Seminole Substation located nearly five miles northwest of Seminole. Construction is expected to begin in 2020.

We are committed to routing the proposed transmission line in a manner consistent with the values of the local communities, the Texas Utilities Code, the Public Utility Commission of Texas Rules and Policies, and the need to provide reliable electric service to the area of North Texas.  Xcel Energy welcomes your input on the proposed routes. 

The Texas Public Utility Commission granted approval for a Certificate of Convenience and Necessity (CCN) for the project before construction January 2019. The CCN process determines the project need and impact as well as the line characteristics, such as substations and endpoints, and the line route. View the CCN filings below.

The Mustang-Seminole transmission line will increase reliability and meet growing needs in the area.

Southwest Power Pool approved a Notice to Construct for the project on August 17th of 2016.  Xcel Energy accepted Notice to Construct November 10th of 2016.

The project is expected to be in-service by September 2020.
